Microchip integrates wireless transmitter with MCU
Janine Love11/28/2011 4:56 PM EST
Microchip Technology Inc. announced the PIC12LF1840T48A—the first in a family of single-chip devices that integrate an eXtreme Low Power (XLP), 8-bit PIC microcontroller with a sub-GHz RF transmitter. The PIC12LF1840T48A is well suited for use in space-, power- and cost-constrained applications, such as remote keyless entry fobs for automobiles, garage doors and home security systems, as well as a range of other home and building automation systems.
Key features:
Price and Availability:
The PIC12LF1840T48A is available today for samples, in a 14-pin TSSOP package, and volume production is expected in January. Pricing: $1.06 each in 10,000-unit quantities.

Is it possilbe to get this type of uC integrated with 12 bit ADC and 0 bit DACs?

WTF? Why do they put a 8 bit microcontroller to compute up to 100 Kbps of data?... why not 32 bits?...

Because the Keeloq(tm) firmware was developped for the 8-bit MCU's,
because the application domain is better served with light programming beit assembly and C,
and most probably because the internal logic interface is already existant in the silicon layout of that family of MCU by Microchip.
